XTR discs with Hop Mono Mini?

I would like to build up a wheelset with DT centerloc SS hubs and Hope Mono Mini brakes. Would I be able to use the XTR disc to benefit from the weight of the lighter discs as opposed to using the 6 bolt Hope rotor with the QBP 6 bolt to C-Loc adapter?
Both discs are 160mm, but I have no idea about the thickness.

In theory, the XTR splined rotor *should* work with the Mono Mini...assuming the thicknesses, outer diameter and rotor braking height are equivalent. I've sucessfully used Formula rotors with my Hope Mono Minis without any issues.

centerlock, lighter?

I do not think that the centerlock rotor will be lighter. Weight weenies lists the XTR centerlock rotor with lock ring at 140 gms. as I recall, and the mono mini rotor with bolts is about 120 gms. Does dt make SS hubs for disc that are not centerlock? If not then you have to figure in the weight of the adapter, maybe that's where you are at. I just posted a thread regarding centerlock rotors to try and determine if there are any performance advantages to them besides the mounting ease. Sounds like you are going to have a trick SS, cool!
